摘要： A method for drilling a well. The method may include detecting stick-slip vibrations at a frequency via a downhole sensor. The method may further include determining a reflection coefficient of a drill bit for the frequency based on at least one of a rotational speed of the drill bit or a torque of the drill bit. The method may also include determining a reflection coefficient of a top drive for the frequency based on at least one of a rotational speed of the top drive or a torque produced by the top drive. The method may further include adjusting a control system in electronic communication with the top drive based on the reflection coefficient of the drill bit for the frequency and the reflection coefficient of the top drive for the frequency.

摘要： A power drill includes a casing, a bit-carrying shaft provided with a front toothed member, a rear toothed member fixed on the casing, a driving unit, and a speed reduction device which interconnects the driving unit and the shaft so as to rotate the shaft at a speed smaller than that of the driving unit. The speed reduction device includes a planetary gear train provided with an internal gear mounted in the casing, and a coiled compression spring which presses the internal gear against an inner wall of the casing so as to fix the internal gear in the casing. An adjustment member is mounted rotatably on the casing and cannot move axially on the casing. The compression spring is located between the internal gear and the stepped portion of the adjustment member. The adjustment member is rotatable relative to the casing so as to compress the compression spring, thereby increasing the push force of the compression spring toward the internal gear, and so as to interengage the front and rear toothed members, thereby urging the front toothed member and the shaft to move forward away from the rear toothed member and providing an impact to an object to be drilled. In use, when the drill unit rotates and when the shaft cannot rotate, the internal gear can rotate.

摘要： A shock absorbing rotary drive coupling assembly for drivingly connecting a drive shaft (19) to an axially aligned driven shaft (21). The coupling assembly has an inner sleeve (17) axially aligned with the drive shaft (19), and in driving engagement with the driven shaft. Bonded to the outer circumference of the inner sleeve (17) is a resilient element (15) which is also axially aligned with the drive shaft (19). Bonded to the outer circumference of the resilient element (15) is an outer sleeve (13). This outer sleeve (13) is connected to a drive plate (11), which is further connected to the drive chuck (21) of the roof drilling machine. During drilling operations, the resilient element absorbs the axial and radial shocks of the drilling. The resilient element (15) also allows for a limited amount of misalignment between the drill steel and the drill chuck.

摘要： The present disclosure is directed to systems and methods for rotating a drill string to mitigate stick-slip oscillations. An embodiment includes a method of rotating a drill string driven by a drive system using a control system. The method includes measuring torque values of the drive system with a torque sensor. The method also includes determining a frequency of stick-slip oscillations at the drive system based on the torque values using the control system. The method also includes determining an estimated instantaneous rotational speed of the drive system with the control system based on at least the frequency of stick-slip oscillations and a characteristic impedance of the drill string. The method also includes adjusting the estimated instantaneous rotational speed based on changes in the torque values to define an adjusted estimated instantaneous rotation speed with the control system. The method also includes providing an output signal representing the adjusted estimated instantaneous rotational speed to the drive system. The method also includes controlling rotation of a quill of the drive system based on the output signal.

摘要： Design parameters for PDC drill bit are correlated to instances of backward whirl, where backward whirl is detected along a lateral axis in the frequency domain during downhole drilling. Two regimes of backward whirl are described and detected—cutting-induced backward whirl and friction-induced backward whirl—where each regime has different characteristic frequencies, detection methods, and mitigation guidelines. Design parameters are quantified by gauge fullness, drilling efficiency (DE), and whirl index (WI). Design guidelines to mitigate backward whirl are generated by correlating design parameter quantifiers and instances of backward whirl, including both cutting-induced backward whirl and friction-induced backward whirl. Potential drill bit designs are then validated against the generated guidelines in order to mitigate backward whirl in future drilling runs.
